I am a student who is interested in biology and Iranian history. I also follow the news and like to create different maps, charts, and shapes based on data. I've created most my diagrams in vector (SVG) format, because of its many benefits. The software that I use for creating the diagrams and drawings are Adobe Illustrator, Inkscape, and CorelDRAW.

English: I am an Officer of the Portuguese Navy, now teaching Cartographic Sciences in the university and doing research on the geometry of old nautical charts. My regular contribution with photos and illustrations to Commons started in 2006. I normally use CorelDraw in my ilustrations and animations

I'm Eric Gaba, aka Sting on Wikipedia, French born in 1966 and live in Brazil. I'm helicopter pilot and photographer.

I joined Wikipedia in November 2004 with my passion for Greek Antique history and in 2005 the Graphic Lab on WP-fr. With the lack of schemes or maps in the project to illustrate articles, I started to learn about Inkscape and create my own pictures. Still not satisfied with my maps due to the difficulty of finding sources of good quality, I heard about Digital Elevation Models provided for free by the NASA or other US government agencies in early 2007. This was really the starting point for me creating good quality maps for the project.

As pilot, I like very much see a map with the representation of the relief as it explains many things : the location of settlements, borders, movement of armies, etc. And the DEMs provided almost all I needed so I got more and more specialized in that area. Gaining experience with the software, I started to extract elevation layers and vectorize them in order to create topographic maps and wrote tutorials to help other contributors to draw maps of different types using DEMs.

I joined Wikipedia in December 2005, and the Atelier Graphique (the French Graphic Lab) in 2007. First it was to create maps of the Marquesas Islands, so I followed the tutorials made by Sting (see above). Then, I continued to draw maps, and also diagrams and schemes, on various subjects.
My favourites softwares are Inkscape and the Gimp, and GlobalMapper & 3Dem for the maps.

I am KDS4444. I like to draw things. I like using Illustrator to do it. I have no background or training in computer graphics or software. I am not an engineer or designer. I have a master's degree, but not in anything related to my illustrations.
